PROCESS FOR THE MANUFACTURE OF ILLUMINATING AND HEATING GAS.

Specification of Letters Patent.

Patented Sept. 10,1907.

Application filed February 13,1907. Serial No. 357,169.

To all whom it may concern:

Be it known that I, GEORGE W. ZIEGLER, a citizenof the United States, residing at Los Angelcs, in the county of Los Angeles and State of California, have invented a new and useful Process for the Manufacture of Illuminating and Heating Gas, of which the following is a specification.

My invention relates to a new and useful process of manufacturing gases of light specific gravities and converting and enriching them into gases of greater densities, so that the resultant product more nearly approaches or resembles a natural gas; and anobject thereof is to provide a process by means of which gases can be manufactured economically for household or other uses.

Another object is to provide a process in which the use of heat as an adjunct to the vaporization of the oils is eliminated.

I accomplish these objects by means of the process described herein and illustrated diagrammatically in the accompanying drawing, in which :the figure illustrated is a diagrammatic view of a form of an apparatus that may be employed in accomplishing my improved process.

Herctofore in the manufacture of gases by carburization it has been impossible to obtain a gas of heavy specific gravity or'one that could be utilized for heating and illuminating purposes. By my process I am enabled to accomplish the manufacture of a heavy specific gravity gas for heating and illuminating purposes in an economical and eflicient manner.

In accomplishing my. improved art of gas manufacture the tank or receptacle 5 is first charged, (preferably about half its capacity) with gasolene, benzene, naphtha or other oils of light specific gravity that are capable of carburization. These oils may be used in combination, such as gasolene and benzene, naphtha and gasolene, or any combination that is found most suitable. Receptacle 5 is provided with an inlet pipe 6 which enters preferably from its top and extends downwardly to within a few inches of the bottom. This pipe is connected by means of a pipe 7 to a blower or force pump 8, connected to a source of power (not shown), by means of which air is forced through the liquid in tank 5.

After the air has been forced through the liquid in tank 5 it is forced by the pressure contained in the upper portion of receptacle 5 through an outlet pipe 9, which isprovided with a globe valve 10 and a check 11 to prevent its return, to a tank 12 which is similar in construction to tank 5, and is provided in its top with an inlet pipe 18. Tank 12 is preferably charged with a heavier grade of oil, such as coal tar-and heavy distillates, and as the vapor from receptacle 5 is forced by the pressure in the tank 5 through the combination of coal tar and heavy distillates it becomes surcharged and enriched, so as to form a rich gas cont'aining a large proportion of hydrocarbons.

From tank 12 the enriched gas is forced upwardly through pipe line 14, which isprovided with a twothat I may change the various proportions of the mixture in the tanks or receptacles without departing from the spirit of my invention. It will also be observed that I have produced a gas that is rich in hydroearbons, and is especially adapted for heating and illuminating purposes, and one that is economical in manufacture.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. The herein described process of manufacturing gas, consisting of passing a volume of air through a body of light gravity oils; and then passing the resultant vaporthrough a body of heavy gravity oils, whereby the vapor so treated becomes surcharged and enriched.

2. The herein described process of enriching carbureted air which consists of forcing a volume of air through a body of light gravity oils, andthen passing the resultant vapor through a body of cool heavy gravity oils, whereby the vapor so treated becomes sin-charged and enriched.

3. The herein described process of manufacturing heating and illuminating gas,- which consists of passing a volume of air through a body of light gravity oils; and then passing the resultant vapor through a combination of heavy gravity oils and coal tar, whereby the vapor so treated becomes surcharged and enriched.

4. The herein described process of manufacturing heating and illuminatinggas, which consists of passing a volume of air through a body of light gravity oils; and then passing the resultant vapor through a body of heavier gravity oils, whereby the vapor so treated becomes sur-' body of heavy 'specific.gravity hydrocarbons, whereby the vapor so treated becomes surcharged and enriched.

In witness that I claim the foregoing I have hereunto subscribed my name this 6th day of February, 1907.

GEORGE W. ZIEGLER.
